The utility model discloses brushless centrifugal fan of direct current simple structure, compactness have reduced the occupation of land space, and are favorable to improving air -out efficiency.

Description

Brushless direct current centrifugal fan
technical field:
The utility model relates to a kind of brushless direct current centrifugal fan.
background technique:
Blower fan is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery, and current blower fan is all made up of motor and the blade be located on motor output shaft, and its structure is comparatively large, and air-out efficiency is low.
summary of the invention:
In order to address this problem, the purpose of this utility model is to provide a kind of brushless direct current centrifugal fan, and this brushless direct current centrifugal fan structure is simple, reasonable in design, is conducive to reducing blower fan volume and improving air-out efficiency.
The utility model brushless direct current centrifugal fan, it is characterized in that: comprise the frame and the conical turbine be located in frame that have into and out of air port, direct current generator is provided with in the body of described conical turbine, the output shaft of direct current generator is fixed on frame, and the main body of direct current generator is fixed on conical turbine.
Further, above-mentioned frame is covered by two cases and forms, and described intake grill is positioned at the side of case, and this side is also provided with the supporting base for fixing direct current generator output shaft.
Further, above-mentioned turbine is made up of both sides ring plate, middle ring plate and the blade be located between two between ring plate.
Further, all sides of above-mentioned direct current generator main body are fixed with annular generator fixed plate, and described annular generator fixed plate border is fixed in middle ring plate.
Further, above-mentioned direct current generator is DC brushless motor.
The utility model brushless direct current centrifugal fan is fixed on frame due to the output shaft of direct current generator, and after direct current generator starts, the body rotation of direct current generator, drives conical turbine to rotate, thus realize air-out.The utility model brushless direct current centrifugal fan structure is simple, compact, reduces and takes up an area space, and is conducive to improving air-out efficiency.
accompanying drawing illustrates:
Fig. 1 is stereogram of the present utility model;
Fig. 2 is explosive view of the present utility model.
embodiment:
Below in conjunction with accompanying drawing and actual mode of execution, the utility model is described in further detail.
The utility model brushless direct current centrifugal fan, comprise the frame 3 and the conical turbine 4 that is located in frame 3 that have into and out of air port 1,2, direct current generator 5 is provided with in the body of described conical turbine 4, the output shaft 6 of direct current generator 5 is fixed on frame 3, and the main body 7 of direct current generator is fixed on conical turbine 4.
Further, in order to reasonable in design, above-mentioned frame is covered by two cases 301,302 and forms, and described intake grill 1 is positioned at the side of case, and this side is also provided with the supporting base 8 for fixing direct current generator output shaft.
Further, in order to reasonable in design, above-mentioned turbine is made up of both sides ring plate 9, middle ring plate 10 and the blade 11 be located between two between ring plate.
Further, for the ease of fixing, all sides of above-mentioned direct current generator main body are fixed with annular generator fixed plate 12 by 6 bolts, and described annular generator fixed plate 12 border is fixed in middle ring plate 10 by 6 self tapping screws.
Further, above-mentioned direct current generator is DC brushless motor.
Frame 3 is also in post shapes, and exhaust outlet 2 is positioned on cylindricality perisporium.Described supporting base 8 supports fixing by three ribs 13.The diameter of conical turbine 4 and the ratio of length are between 1.15-1.20, and this ratio air-out effect is best.
The utility model brushless direct current centrifugal fan is fixed on frame due to the output shaft of direct current generator, and after direct current generator starts, the body rotation of direct current generator, drives conical turbine to rotate, thus realize air-out.The utility model brushless direct current centrifugal fan structure is simple, compact, reduces and takes up an area space, and is conducive to improving air-out efficiency.
The foregoing is only preferred embodiment of the present utility model, all according to the utility model claim accomplish change with modify all should belong to covering scope of the present utility model.
